Assalamualaikum.I am a first time mother to a 23months old baby.this is my second breastpump.Alhamdulilah it perform well for 15months.when suction became abnormal,I went straight to the centre.after sales service consultation was great.they rule out one by one in order to specifically \'diagnose\' the problem.the service centre is coincidently nearby my house,5 minutes walking distance.thank you very much
